2394Wh Capacity for Extended Endurance Under Extreme Loads

Delivers stable, high-intensity flight performance for nearly 6 minutes even under maximum takeoff weight conditions of 101.4kg, ensuring reliable operation in the most demanding scenarios.

Resume Operations in 9 Minutes with 5C Rapid Charging
Rapid 5C charging reaches 95% capacity in 9 minutes from 30%. Achieve 5–6 complete flight cycles per hour versus 2–3 cycles with standard charging, increasing daily productivity by up to 150%.
Effortlessly Lift 100kg Payloads with 280A Continuous Output
9C peak continuous discharge with 280A sustained current delivers consistent thrust for agricultural and cargo drones, maintaining stable hover and maneuverability even at maximum payload.

20% Faster Cooling Enables Immediate
Recharge After Landing

Increasing cell energy density relies on enabling the cathode to operate stably at higher voltages. Through surface coating and elemental doping, we protect the cathode from electrolyte corrosion and reinforce its crystal structure. This extends the electrochemical window to 78.3 V, enabling safe high voltage operation with more energy and long cycle life.

1000-Cycle Lifespan Cuts Battery Cost Per Flight by 60%

When paired with TATTU chargers, intelligent temperature management automatically adjusts charging current based on real-time conditions, preventing damage and extending battery life to 1000 cycles compared to typical 400 cycles.
